I hadn't even realized GitHub had changed. Thanks for this extension. Rounded corners reminds me of flat design back in 2012-2013 when Windows 8 was released and designers moved away from skeuomorphism (3D, distinct, colorful buttons and design), suddenly flat design was everywhere. We've just gotten used to it now they're adding rounded corners everywhere!

Android 12 compared to 11 is very ugly for example, please stop the round design, especially Material You design!

Rant over.

It doesn't fix everything, but it improves it massively and works fine.

a huge improvement on github's new design. thank you!
